Fuel economy 2.7 D3/4

[scarry]

Interested to find out what sort of fuel economy you guys are getting from 2.7 D3 or D4,not towing.

Forget what the dash readout says,it is inaccurate.
If mine says 9.5l/100 it is actually doing around 10.5l/100.

On a run,can't seem to get less than high 10's,nothing on roof & lightly loaded.

Around town,generally mid 13's.

[Weird Al]

My D4 2.7 gets 9.2 (7.5 to 8.0 indicated) on the highway.

And around town between 10.5 and 11.5.(9.0 to 10.0 indicated)

Although its a but hard to tell whats what with the long range tank now fitted, for example last time I filled the car it took 181.9L to cover 1862.1km, so 9.77L/100k.

Consisting of a trip to Sydney and back, a trip to Wagga and back and the rest driving about the nations capital.

This is with one person and bunch of work crap in the back, or two large and two small occupants.

Pretty good for a 2.5T brick shaped motor vehicle.

Perhaps your BFG's add a bit to the consumption, they added an extra L/100 to my previous car a Grand Cherokee.

[ADMIRAL]

We did 2800klms recently, heavily loaded, including a large brick on the roof, to stuff up what was left of the aerodynamics.

The vehicle readout gave us 11.4 litres per 100 klms, the fill to fill worked out at 11.5 litres per 100klms. That is pretty accurate.

I find the std tyres with the calibration as delivered, read hopelessly under. Almost 10% out at 100kmh. ( by GPS ) We ran 17"rims for the trip, and 275/65 muddies. The speedo is now pretty much spot on. Probably had a fair bit to do with the results achieved.

Usually ours gets about 12.5 l/100 for everyday driving, not as economical as others seam to get given that we live in the country with few traffic lights and no rush hour traffic.

Highway driving is very good however as far as I'm concerned with about 9.5 to 10.5 l/100 depending on how I drive.

I have 265/60/18's fitted so the speedo is pretty much accurate.

cheers,
Terry

My D4 2.7 gets (says the trip computer) 10.4 around town and 8.4 on the highway. Adding the Rhino rack adds another 2.

Having nursed (for economy) the D3 V6 petrol around town for 5 years I still try to use a very light foot when accelerating.

Thanks for the replies

Weird al,i thought about the BFG's,but had them on the D2 & it got fantastic fuel economy,actually a lot better than the D4.I had the OEM 18's on (the D4) for a while & fuel economy was the same as the BFG's.

Admiral,so as my tyres are same diameter as OEM,that is maybe why dash read out is also incorrect,as speedo is definitely reading faster than actual ,as per my GPS,around 5%.Dash readout of fuel usage is around 10% out at least.

Terry o,your highway fuel econ is way better than mine,and i don't go over 100k's & drive smoothly(i could get 8's out of the D2 TD5)

White D3,ever actually checked it against your dash readout,you may get a surprise.:o

Be good to get a few more replies,mine has only got 6000k's on the clock,maybe will improve a bit more hopefully.

[WhiteD3]

White D3,ever actually checked it against your dash readout,you may get a surprise.:o

I have. It reads ~ 0.5 to 1.0 l/100km low. 'bout the same error as the D3 I've found.

The problem in doing a real world comparison is not knowing how the carputer calculates the economy (time, distance travelled, etc). I've looked for but not found an explanation.

[roamer]

I have 3lt and have noticed varying economy with different fuel supplies.
BP Ultima much better.
For what its worth 9l\100km at home (countryish) and
13.2 l/100km towing a 2ton KK ( 5000km trip)

My 3.0's odometer was very accurate even though the speedo was about 5% optomistic due to the factory-set speedo fudge factors in the CCF prior to my changing them. Unless you have already taken account of it, your distance travelled with the larger tyres is likely to be low so your fuel consumption should be less than what you have calculated.

[PKD4]

Hi Scarry,

My TDV6 isn't that much older than yours, done 13000kms. Stock tyres.

Like some others real fuel usage is about 1.0L more than trip computer calculates.

According to the computer:
Highway with moderate internal load I get 8-8.5L/100km(so 9-9.5 actual)
Highway with roofracks stacked with surfboards - 9-9.5L/100km(10-10.5)
Around town(regional) - 12-12.5L/100km(13-13.5).

Oddly, despite the L/100km underestimating consumption, I feel that it also underestimates distance to empty, based on what it takes to fill. Mind you, I don't think I will try to put it to the test

Cheers,
Pat

Only had the 225000 klms TDV6 D3 for a coulpe of months around town 11.1 indicated 11.7 actual

[Geedublya]

Average L/100 is 13.901 this is mainly stop start traffic for 40 mins each way weekdays.
Highway L/100 is about 11.5.

Car has ARB front bar, Warn winch, Kaymar rear bar with usually single but sometimes double carriers and wheels, dual batteries, 105L long ranger and runs 265/60 18 Cooper ATRs. No racks on it usually.

[PeterOZ]

I have a 2007 TDV6, about 140,000 on clock. Normally use BP Ultima.

Tyers are Pirelli Scorpion Zero 255/60 R18 112V

Around city (Brisbane) I average about 10.6 - 11.2, I tend to drive it hard!

Highway cycle, approx 110kmh (where permitted of course :cool:) it gets about 7.6 - 8.

Gets much worse when towing my heavy trailer for my model planes. Have not really checked that consumption.

After a refill, trip meter reset and rolling down a hill... What do you mean it isn't helpful or accurate? :p

Ok... We are getting an indicated 8.4 mixed use now after the Viezu performance remap. Lots of short trips as well as the odd (10 min) freeway run.
Better than my tuned Golf (10.5) 2.0 Turbo and better than my wife's Volvo (11.5) 2.4L NA.
Pleasantly surprised after switching to a much bigger car.

ARB front bar, Cooper Discoverer HT Plus.

What are you guys using to get a real time/ accurate readout - a scangauge?

[Geedublya]

I use a scanguage which is great if you can be arsed to keep plugging in the info and don't do partial fills.

I also use an app called aCar to track fuel usage and as my logbook. It gives statistics, charts, predictions and can be exported to excel if you want to go the full nerd.

[Disco4SE]

Managed this in my D3
Mind you, I had filled up not that far back down the road
